Isostatic graphite is a type of graphite with an ultra-fine grain. It is used for applications where the mechanical properties of other fine-grained graphites are inadequate.

In semiconductor manufacturing, the precision and stability of the etching process are paramount. One critical factor in achieving high-quality etching is ensuring that wafers are perfectly flat on the tray during the process.

Currently, silicon carbide (SiC) is a highly active area of research in thermal conductive ceramic materials both domestically and internationally.

The development of high-powered blue and UV LEDs has enabled the creation of full-color LED TV displays, as well as white LED automotive and domestic lighting. These LEDs are based on Gallium Nitride, which is deposited on substrate wafers supported by CVD SiC-coated graphite susceptor using the MOCVD process.

Silicon carbide substrate is a compound semiconductor single crystal material composed of two elements, carbon and silicon. It has the characteristics of large bandgap, high thermal conductivity, high critical breakdown field strength, and high electron saturation drift rate.

Tantalum carbide coating is an important high-strength, corrosion-resistant and chemically stable high-temperature structural material with a melting point of up to 4273 °C, one of the several compounds with the highest temperature resistance. It has excellent high-temperature mechanical properties, resistance to high-speed airflow scouring, ablation resistance, and good chemical and mechanical compatibility with graphite and carbon/carbon composites. Therefore, in the epitaxial process of GaN LEDs and SiC power devices such as MOCVD, TaC coating has excellent acid and alkali resistance to H2, HCl, NH3, which can completely protect the graphite substrate material and purify the growth environment.
